Mexico has always failed to flourish for one reason or another.

The collective American guilt over the Mexican-American war is overblown. Mexico was a poor excuse for a country before the war as after it.

Something that the liberals are correct on is that Mexico is out problem and that too harsh of a response will make the situation in Mexico worse and thus worse for us on our border.

That isn't to say we shouldn't take strong measures at this point in time however as we simply cannot allow things to continue as they have for the past 40 years. At the same time Mexico's failed economy is not an excuse for American cultural suicide.
